643-1497: 35mm Outer Diameter Cylinder Head Valve Stem Seal

The Cylinder Head Valve Stem Seal is designed to prevent oil from entering the combustion chamber while ensuring proper lubrication of the valve stem within an internal combustion engine. By maintaining a tight seal around the valve stem, the seal prevents oil leakage, which could lead to increased oil consumption, fouled spark plugs, and reduced engine efficiency, by facilitating adequate lubrication of the valve stem, the seal helps to minimize friction and wear, thereby extending the lifespan of engine components. Attributes: • Withstands high temperatures to prevent seal degradation. • Minimizes wear and tear on valve stems. • Ensures a tight seal around the valve stem. • Resilient against engine vibrations. Applications: The Cylinder Head Valve Stem Seal is used to prevent oil leakage and maintain proper lubrication within the engine's cylinder head by sealing the gap between the valve stem and the cylinder head.
